CONCORD — A teenage bicyclist died Sunday after colliding with the driver of a pickup truck, police said.

The fatal collision happened around 6:51 p.m. on Willow Pass Road at the intersection of Fry Way, and the 16-year-old Concord boy died at the scene, police said. He has not been identified.

The 40-year-old Fairfield man driving the pickup truck was going west on Willow Pass Road and approaching Fry Way when the crash happened. He stopped to call police and has been cooperating with the investigation, police said. Police do not believe alcohol or drugs were a factor.

The bicyclist went northbound on Willow Pass Road and was in the west crosswalk at Fry Way when he was hit.

Investigators have not determined the cause, and police were unavailable for comment early Monday.
